LOCKING MEANS FOR INTERNABCOMBUSTION MOTORS.

To all whom it may concern lie it known that I, OASIN \V. OBERT, a citizen of the United States of America, and

city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Looking Means for Internal- Combustion Motors, of which the following is a specification.

This invention relates to locking means for internal eomlmstion motors so as to render such motors inoperative, and thereby prevent the unauthorized use thereof.

The object of this invention is to provide such a combination of parts that the locking into inoperative position may be carried out without danger of injury to any of the operative parts, and at the same time provide such means that the locking is entirely secure and reliable.

For this purpose the invention consists of certain novelfeatuies and combinations of parts which will be more fully described and finally pointed out in the claims.

'In the accompanying dra\\'ings,Figure 1 isa sidevicw of an internal-combustion engine showing my invention applied thereto, in

, connection with an ignition device known in practice as a magneto, Fig. 9. is an enlarged view of my invention in detail, Fig. 3 isanother embodiment of my invention applied to the shaft driving a timer of an internaleomtmstion engine, Fig. 4 is another embodient of my invention applied to the member driving the ignition operating shaft in the gear-case of an internal combustion motor, Fig. 5 is another embodiment of my invention applied directly to the timer for such an internal combustion motor, and Fig. (3 shows another embodiment of my invention applied directly to the magneto and operating in a slightly ditl'erent manner, but accom 'ilishing the same result as the other embodiments shown. in the various figures.

Similal refe ence characters indicate corresponding parts throughout the differentfigures of the drawings.

Referring to the drawings, and more particularly to Fig. 1, where a side-view of an internalcombustion motor of approved con struction is shown. the parts therein shown as forming part of the iuternal-combustion motor are all well known and will only be briefly referred to. The casing 10 is pro vided with cylinders 11 and shaft 12 having flywheel 13 thereon.

with the shaft 12 is a second shaft 15, which as heretofore constructed was a single unbroken shaft, the rotation of which would rotate the members constituting the magneto 16 so as to produce the necessary sparking for the ignition function.

An embodiment of my invention is applied to the shaft 15, shown in Fig. 1, and consists in providing means for throwing a part of the shaft out of engagement with another part, and then locking the part,

when thrown out of engagement, into that position. Or it may also be embodied in a structure where the parts are locked in po sit-ion during the operation of the motor, and then when it is desired to place these parts into inoperative position the members are unlocked, whereby suitable means bring about the disengagement of the two members necessary for the transmission of the motion from one end ofthe shaft to the other, an embodiment of which other form is shown in Fig. 6.

Referring again to Fig. 1, the shaft 15 is divided into twoparts, one part of which has secured. thereto the recessed member 18 which is secured to the shaft 19 by the key 9.0, and thereby follows at all times the rotation of the shaft 19. A second member 21 is provided with a key-portion 22 whichengages a slot 23 arranged in the shaft 15, as clearly shown in Fig. 2, whereby said member 21 is movable longitudinally along the shaft 15, but is prevented from rotating in respect thereto. A yoked member 24 engages the sleeve 21 so as to move it along the shaft 15. This yoked member 24 is support ed by and pivoted to the shaft 25, which shaft is suitably supported in the walls of the casing 26. The yoked member 24 has an extension 27 which is engaged by the locking bearings 32 at either side thereof to permit the shafts 15 and 19 to pass thcrethro'ugh,

and the said casing 26 is suitably supported on the, casing 10 of the internal-colnbustion engine.

\Vhcn it is desired to operate the internalcombustion. motor, the locking bolt 29 withdrawn. and therebyth coiled spring, shown in Fig, 2 and indicated therciniby- .1 cxertsits force against the slidable sleeve and brings this sleeve 2-1 into engagement with its locking member 18 so as to lock the the member 21 disengaged fromthe memher 18, and the spring 35 correspondingly compressed, whereby the shaft 15 is free to move independently of the shaft 19 for a short time until the rotational energy there in expands itself, when the engine comes to a standstill when the parts are so locked, no unauthorized person can operate the motor, and this becomes especially important in connection with automobiles and motorboats.

In Fig. 3 another embodiment is shown, wherein the locking parts are arranged upon the shaft that drives the timer 40 of a suitable and approved construction. The parts are substantially the same as those shown in Fig. 2, the shaft 19 being provided with a recessed locking member 18 engageable by the locking member 21 having its circumferential cut-out portion 37 engaged y the yoked member 24;, which is pivoted to the shaft 25. The shaft 15 is also provided with the slotted portion 23 to prevent the locking member 21 from rotating, which locking member is provided with a suitable key (not shown in this figure). In this embodiment the extension 27 instead of being acted upon directly by the locking bolt, is connected with a rod 38, which is in turn connected with suitable locking mechanism within handy reach of the operator (not shown in the drawings as the 0peration thereof is very' clear).

. In Fig. 4- substantially the same mechanical parts as those shown in Fig. 2, are shown, but they are applied directly in the gear-case to a gear that drives the ignition operating device, be it magneto, timer or other form of ignition. .The gear 42, shown in Fig, .4, is provided with the clutch-portion 18, jengageable by the clutch-portion 21 movable by the yoked portion 24, which is again pivoted to 25 and has an extension 27, In the embodiment shown in Fig. 4, the extension 27 is provided with a pin 43 which passes thcrethrough and through the look ing bolt 29, which locking bolt is operated by suitable locking mechanism 30.

In the embodiment shown in Fig. 5 substantially the same parts are again shown, but these are connected to-the base of'the timer, the clutch-porti n 18 being innncdiately connected therewith, which is engageahl by the clutch portion 21. In Fig. 5, a suitable collar 44, fixed in positio b a thumb-screw 45. is provided.

In the embodiment shown in Fig. 6, the casing 26 with the locking mechanism is arranged close to or as a part of the mag-- neto, but in this case the operation is slightly different from the operation of the parts described in connection with Figs. 1

t0 5. Instead of having the spring press the movable clutch member against the fixed clutch member, the spring, now indicated in Fig. 6 by 46, tends to draw the movable clutch member 21 away from the fixed clutch member 18. In order to maintain the tWo clutch members in locking engagement with each other, the yoke 24 pivoted at 25 is locked in the position shown in Fig. 6 by having the locking bolt 29 of the locking mechanism 30 connected by the pin 43 to the extension 27. When the parts are so locked the clutch membcrs'18 and 21 are brought into locking engagement with each other; but when it is desired to bring these clutch members out of locking engagement with each other, the bolt 29 is moved still farther out of the lock 30 and the yoked member 24 thereby is free to move and is moved by the movement of the bolt 29, the spring 46 tending to pull out the clutch member 21 away from the clutch member 18; but it will be seen that in principle the operation of the parts in Fig. 6 is the same as that shown in Figs, 1 to 5, and this principle is applicable to any of the forms of mechanism in Figs. 1 to 5.

From the above it will be seen that the basic idea of looking a gasolene or other form of internalcombustion motor in inoperative condition, consists in providing any suitable form of mechanical lock, latch, key, disconnecting link or clutch, or other detachable mechanism on the shaft thatdrives the timer, magneto or other ignition device. The applications of this idea to commercial forms of mechanism on typical motors may be as shown in the embodiments, which show the application of a locking function to be provided for by any form of lock and key mechanism or any form of easily or quickly operated latch, or other mechanical means for locking or unlocking, which, however, differs from a temporary alteration of this apparatus.

I have shown various embodiments of my invention, but changes may be made therein without departingfrom the spirit of the in vention as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1.
